I am not sure how you pin those apps into your start10 but for me, I can get it to shows its listed item on the right panel of Start10. And for those apps with recent files opened list. Like Excel, Word, Media player, it will have it on the right also. All link with that white/gray arrow will have something listed on the right panel when your mouse hover over it.
For me, I usually use the "Pin to Start menu (Start10)" with a right click on the program I wanted to pin on it.
